LLM streaming UI, agent surfaces, prompt flows, eval dashboards, AI copilots. Frontend for AI products that ship past the demo.
Embed a senior frontend engineer.
Embedded frontend engineering for B2B SaaS, AI, and data-heavy products. React, Next.js, React Native. Month-to-month. You own every line of code.
Founders and Product Teams We’ve Shipped With
Frontend is where most product roadmaps quietly slow down.
Senior hires take months to vet and ramp on your codebase. Design handoffs drift through every sprint. Marketplace and contractor work ships code that rarely compounds into a system your team can build on.
Denovers is a senior-only embedded studio. Engineer in your Slack inside 48 hours, designers and engineers under one roof so handoffs don’t drift, and the first surface ships as a real PR during a free 7-day trial.
SaaS dashboards
Responsive dashboards, tables, filters, charts, cards, modals, sidebars, and complex product screens.

Design system components
Reusable frontend components built from your Figma design system for faster, more consistent product development.
Responsive web apps
Frontend interfaces that work properly across desktop, laptop, tablet, and mobile breakpoints.
Admin portals and internal tools
Role-based portals, CRMs, management dashboards, approval flows, settings, and operational interfaces.

Production React across the surfaces founders bet their roadmap on.
Five product categories. Real frontends our embedded engineers shipped, end-to-end, into production codebases.
YC-portfolio rebuilds, dental health-tech, AI neurology, role-based access, compliance-aware React in regulated environments.
Multifamily SaaS, multi-role investor portals, internal CRMs, real-estate data analytics. One acquired client closed at the end of the engagement.
B2B payment rails, climate fintech, remittance customer + agent apps, financial modeling. Bank-grade React across multi-tenant deployments.
Onboarding rewrites, retention loops, dashboard rebuilds, design-system implementation for B2B and creator-economy SaaS at scale.
From the discovery call to your first commit, in two days.
No staffing email chains, no resume PDFs, no marketplace shortlist to interview. Muzammil runs discovery, matches the engineer, and the trial sprint starts inside two business days.
Call with Muzammil
30-minute discovery call with the founder. Your stack, your codebase shape, the surface to ship in the trial, your stand-up cadence. No SDR, no funnel, no pitch deck.
Engineer matched + NDA
You receive one named senior engineer matched to your stack and the trial surface. NDA + IP-assignment language signed. Slack, GitHub and Linear access provisioned by your team.
Embedded, first commit
Engineer joins your daily stand-up, reads the codebase live, opens the first branch and pushes a first commit by end of day. Trial sprint clock starts.
Trial PR shipped, you decide
One real surface from your roadmap shipped as a production-ready pull request. End-of-week readout with Muzammil. If it’s a fit, the monthly retainer starts. If not, you keep the code and we part ways. No fee.
48 hours from the call to your engineer in Slack. 7 days to evaluate the work at no cost.

Start a free 7-day trialEvery engagement starts with the free 7-day trial.
The trial is the front door. 48 hours from the discovery call to first commit, then 7 days for the engineer to ship a real surface into your repo at no cost. Stay on retainer if it's a fit. Walk if it isn't. You keep the code either way.

Built on the stack your team already uses.
We work with the tools product teams already use to ship clean, scalable, and maintainable interfaces.
The questions CTOs ask before they hire a frontend engineer here.
Ten straight answers. The 48-hour start, the free trial, stacks, scope, ownership, code review, taking over a codebase, non-React stacks, and how this beats marketplace hiring.
How is 48 hours possible?
Because the discovery call is with Muzammil, our founder, not an SDR. Hour 0 is a 30-minute call on your stack, the trial surface, and stand-up cadence. Hour 24 is a named senior engineer matched to your stack, NDA + IP-assignment signed, your team provisioning Slack and GitHub access. Hour 48 is the engineer in your daily stand-up, reading the codebase live and pushing the first commit by end of day. No marketplace shortlist, no resume PDFs, no funnel.
What does the free 7-day trial actually deliver?
One real surface from your roadmap, shipped as a production-ready pull request into your repo. No fee. The engineer joins your Slack and stand-ups on day one, reads your codebase on days one and two, and starts shipping by day three. Daily async stand-ups, end-of-week readout with Muzammil. If the work, the seat, or the fit is wrong, you walk for free at the end of the week and keep the code. If it converts, the monthly retainer starts the following Monday.
Why not just hire from a senior-engineer marketplace?
Three reasons. Speed: marketplaces still take 1 to 3 weeks of shortlisting and interviewing before first commit; we are at first commit in 48 hours. Embed depth: marketplace engineers tend to default to async contractor mode; ours join stand-ups, code review and release rituals from day one. Design taste: every Denovers engineer ships beside our designers daily, so they read Figma like a spec and own the component system instead of recreating it. Marketplaces sell engineers alone. We don’t.
What stacks do your frontend engineers work in?
React first, then Next.js (App Router, Server Components, streaming SSR), React Native and Flutter for cross-platform mobile, Angular for enterprise rewrites and legacy modernization, and Node.js for the BFF layer between your existing backend and the UI. TypeScript across all of it. Shipped production React in every B2B context we work in: data-heavy SaaS, AI-native products, multi-tenant fintech, healthcare data middleware, internal CRMs, and remittance apps live with 250K+ customers.
Do you also design, or only ship code?
Both, under one roof. Our frontend engineers have shipped beside our designers for years, so they read Figma like a spec, push back on a flow that won’t ship, and own the component system instead of recreating it. If you need design and engineering on one timeline, the Embedded Pod is built for that. If you only need an engineer, the Embedded Engineer tier is one seat. See our Embedded Design Team service for design-only retainers.
What if the engineer isn’t the right fit after the trial?
You walk for free at the end of the trial. No fee, no claw-back, no minimum-engagement penalty. You keep every line of code shipped during the 7 days under your license. If the fit was close but not right, we can also propose a different engineer for a second free trial week. Most teams either convert after week one or walk; the second-trial path is rare but it exists.
Who owns the code your engineers write?
You. Every line of code we ship is in your repo, under your license, with your commit history. There is no Denovers-owned framework you have to keep paying for, no licensed component library that locks you in. You can cancel the engagement at any month and the codebase keeps shipping with your internal team. We sign IP-assignment language in every MSA.
How do you handle code review and CI?
We follow your conventions. Our engineers push PRs through your existing review process. Two-eyes review, your CI green before merge, your release manager calls deploys. We write tests at the bar your team writes them. If you need us to set up Vitest, Playwright, React Testing Library, or visual regression with Storybook because nobody has yet, we will do that as part of the engagement, but we do not impose it where your team already has a working system.
Can you take over an existing React or Next.js codebase?
Yes. We do this often. Repurpose.io was a full rebuild on top of an existing creator-economy SaaS now serving 20,000+ paid users. CoVerified was 100+ screens of React added on top of an existing Laravel/Lumen + AWS backend in 6 weeks. RLCore was a wireframe-grade MVP we modernized into a launch-ready dark-theme industrial-control platform. Our engineers spend the first week reading the codebase before pushing structural changes.
Do you work with non-React stacks (Angular, Flutter, Vue)?
Angular for enterprise rewrites and legacy modernization (most often Angular to React migrations on a phased rollout). Flutter for cross-platform mobile where the team has already chosen Flutter; otherwise we lead with React Native. Vue we touch only when the codebase is already Vue and a full rewrite is not on the table. The core competency is React and Next.js; the adjacent stacks are real, just not the lead-with.
